COOLER'.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Be it known that I, BENJAMIN BRIsooE, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Coolers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to coolers more especially designed for the dissipation of surplus heat from explosion-engines and of that type in which a fluid circulating medium is employed.

It is the object of the invention to obtain an inexpensive construction to manufacture and at the same time one which has great efficiency, especially under the varying conditions imposed in its use on motor-vehicles.

The invention consists in the construction and arrangement of the fluid-circulating conduits; further, in the construction of the radiating flanges used in connection with said conduits, and, further, in the peculiar construction, arrangement, and combination of parts, as hereinafter set forth.

In the drawings, Figure l is a cross-section through the cooler. Fig. 2 is a perspective view of some of the parts detached. Fig. 3 is a plan of the blank from which the radiating flange is formed, and Fig. 4 is an enlarged cross-section through said flange.

With my improved construction prior structures are greatly simplified by employing flattened liquid-conduits and forming the transverse air conduits by peculiarly arranged wings or flanges.

As shown in the drawings, A and B are two headers arranged parallel to each other, and C designates flattened liquid-conduits extending between said headers and joined thereto. Each of the conduits C is preferably formed of a sheet-metal tube, which is fiattened so that the parallel walls a and b are in close proximity. This tube may be formed from sheet metal, the blank having the opposite edges thereof seamed together at c, and the seam is preferably arranged centrally of the conduit, so as to form an inwardly extending rib which serves to space the walls a and b from each other. If desired, these walls may be further held spaced from each other by the arrangement of one or more intermediate ridges d, formed in the sheet metal, as shown in Fig. 2.

Another advantage of the construction in the inwardly-projecting ribs or ridges is that in case of freezing the ribs afford an expansion for the conduit Without danger of rupturing its walls or destroying the flanges, about to be described, which are sleeved thereon.

The conduits C are arranged in series parallel to each other and each is provided with radiating flanges, said flanges together serving to divide the space intermediate the conduits C into a multiple of transversely-extending air-conduits. Each of the flanges D is preferably formed from a sheet-metall blank e, which is slitted atj and is also bent u on the line g, so as to form oppositely-angling flanges h and 'i'. The radiators thus formed may be sleeved upon the conduit Cby passing the latter through the slitsf, and by arranging said radiators with their flanges alternately angling in opposite direction triangular-shaped air-passages 7c will be produced on opposite sides of said conduit. f

Each of the conduits C is preferably provided with a series of the radiating anges D, and the flanges of adjacent series preferably interlock with each other. To facilitate this engagement, one end of each iiange is preferably flattened, as shown in Fig. 4, to form a tongue Z, and this tongue is readily inserted between the flanges of the adjacent series.

When all of the conduits C are provided with the flanges I), as described, the structure as a whole comprises a series of parallel flattened liquid-conduits and a series of transversely extending air conduits completely filling the space between the liquid-conduits. Thus when the cooler is arranged, as is usual on motor-vehicles, with the air-conduits extending longitudinally of the vehicle the aircircuit caused by the forward motion of the machine will be passed through the multiple of air-conduits, cooling the water-conduit C both by direct contact and by indirect contact through the medium of the flanges D.

In order that the cooler may be efficient when the vehicle is at rest as well as when in motion, the flanges D are preferably perforated, as at m. These perforations ermit of a circulation of air through the coo er in a transverse direction to the air-passages 7c or IOO in substantially the same direction as the circulation of the fluid in the conduit C. As a consequence, if the air is in motion in any direction a circulation will be permitted through the cooler, or a circulation will be induced merely by the heating of the air.

What I claim as my invention is- 1. In a cooler, a liquid-conduit comprising a flattened tube having the parallel walls thereof in close proximity, and an inwardlyextending rib on said tube for holding said parallel walls spacedfrom each other, and a radiating flange sleeved upon said tube.

2. In a cooler, the combination of a liquidconduit formed of a flattened tube having parallel walls thereofv in close proximity, and an inwardly extending rib on said tube formed by seaming the adjoining ends of said tube, vfor holding said parallel walls spaced from each other.

3. In a cooler, the combination with a fiattened liquid-conduit of a radiating flange therefor, formed of sheet metal struck up to form oppositely-angled flanges, and slitted at the angle to be sleeved on said conduit.

4. In a cooler the combination with a flattened liquid-conduit of a plurality of radiat-A duit, of a radiating flange therefor, struck up A to form oppositely-angled flanges, and apertured through the angle portion to be sleeved on said conduit.

8.- In a cooler, a series of liquid-conduits and oppositely-disposed radiating flanges arranged in criss-cross fashion in the space between the conduits to form a series of closelyassociated air passages therebetween, said flanges being apertured for the reception of said conduits.

9. In a cooler, -the combination of a liquidconduit comprising a flattened tube having parallel walls in close proximity and a radiating flange sleeved upon said tube of an inwardly-extending bead or corrugation in the wall of said tube, the said bead or corrugation constituting a means for holding the parallel walls spaced from each other and affording a means of expansion for said conduit in case of freezing.

lIn testimony whereof I affix my signatur in presence of two witnesses.
